To expand on Bjorn's comment. I participate on a bird photography site where every image is critiqued, and it can seem a bit negative at times, but almost without exception the comments are given in a positive manner, with the intent of providing useful feedback, not just a "great shot" slap on the back, which is boring to read, and doesn't help the original poster learn and grow
And, the nice bit about doing thoughtful and detailed critiques, is it helps the person doing the critique as well. To do a good job with the comments, you need to really study the image, and think about what works, and what doesn't. This will help in your own images
Merry Christmas to everyone.
Cheers
